[Jimla]

New AT3 FF-ML 20 Inch Faxon 6.5 Grendel Upper Range Result:

Hornady 123 SST with 27.0-27.9 IMR 8208 XBR Results, was going to try 28.0-28.4 but too much sun for Chrono to work reliably, too much risk of over pressure 27.9 looked like it had ejector marks.

27.0-27.4 had very similar Point of impact (I think the node was in the 27.0 or 27.1 area)

27.7-27.9 Had small groups but double the Point of impact shift

27.0 IMR 8208 XBR 0.68 MOA
27.7 IMR 8208 XBR 0.56 MOA
27.9 IMR 8208 XBR 0.70 MOA

typical group size was .85 MOA for the 27.0-27.9 range
